I could technically use my new planner I bought for 2010, since the 1st is on a Friday, and today and tomorrow are visible on the first page. But I'm not quite ready to let go of my old planner yet. We've been many places together, and I wouldn't change any of them. The past year and a half of my life is represented in that book. I could let it go today, but I think I'll wait until tomorrow.
